SPECIFICATION forming part of Letters Patent No. 400,803, dated April 2,1889. Appltli filed September 3, 1888. Serial No. 284,406. (No model.)

To` aZZ whom t may concern:

Be it known that I, HIRAM C. STOUFFER, a citizen of the United States,residing at Mineral Ridge, in the county of Trumbull and State of Ohio,have invented new and useful Improvements in Picks, of which t-hefollowing is a specification.

My invention is directed to improvements in picks more particularlyadapted for use in mining, and in which the pick-head is secured forready removal and replacement by a new one when worn out; andthe objectsof my improvements are to provide a firm fastening for thehandle-socket, to afford facilities for the adjustment of thesocket-fastening device, to compensate for the shrinkage and loosenessof the handle and maintain the firm connection of the latter with thesocket, and to provide a firm connection of the pick-head with thehandle-socket. I attain these objects by the construction illustrated inthe accompanying drawings, in which- Figure l is an elevation of theprick. Fig. 2 is a sectional View. Fig. 3 is a view in perspective ofthe handle-socket, showing the means whereby the socket-fastening devicemay be adjusted to maintain .the firm connection of the socket With thehandle.

The metallic socket part a receives into its socket the enlarged end ofthe handle, and is riveted thereto at b. As this riveting is notsufficient to maintain the firm connection of the socket part with thehandle, I construct the socket part to receive one or more supplementalfastening devices, which I will presently describe. The outer solid endof the socket part is recessed at c, vso as to leave flat bearing partsd CZ at each end, from the face of which pins e e proj ect. The sockethas a central screw-threaded opening, f, in its outer solid end, andbetween it and the end projections, d d, it is formed with openings g g,which extend through the solid end into the socket proper, so that thehandle is driven into the socket over the inner ends of these openings.Through these openings metal wedges h h(one or more) are driven into theend of the handle at its junction with the solid end of the socket, soas to spread and bind the end of the handle firmly within the socket. Asthe handle shrinks, or from other cause the socket part should becomeloose, these wedges may be tightened by driving them farther through theopenings into the handle by removing the pick-head.

In this way the handle can be kept firmly bound within the socket, andthe riveting is reenforced, so as to tighten the wood around it.

The pick-head sets solid and flat upon the flat end bearings, d d, ofthe socket part, and 6o it is formed with holes t' t' in its inner sideto receive the pins e e, which project from said end bearings. Thisgives a firm bearing of the pick-head upon the fiat ends only of thesocket part, so that when the pick-head is secured by a screw, Z,passing through a central opening, m, in said head and into. thescrewthreaded hole f in the solid end of the socket the pick-head will'be firmly secured, so that it may be readily removed and replaced, or 7oa new picl -head secured upon the socket when desired. The centralopening in the pick-head is recessed at the outer side to receive thehead of the bolt.

The pick-head is secured upon the socket part over the openings and thewedges therein, whereby should the Wedges become loose they are retainedin place, and can be tightened by driving them farther into the handlethrough openings in the socket. the wedges are made adjustable, andtheir ends are always exposed in the openings, so that they may bedriven farther into the handle when required. For this purpose theopenings are permits the wedges to be driven so as to be free of thepick-head and give ample room for their adjustment. By having the recessin the socket end the pick-head will have no In this way 8o about aninch in depth, which bearing upon the latter, except at its flat 9o andshould the handle be- IOO I claim as my improvementl. A socket part forpick-handles, having its solid outer end provided with openings g g oneach side of a central screw-threaded hole, j, in combination with thehandle, and 011e or more wedges, h, driven into the latter through saidopenings, substantially as described.

2. A socket part for pick-handles, having its solid outer end providedwith openings g g on each side of a central screw-threaded hole, f, andhaving flat end bearing parts, CZ CZ, each having a projecting pin, e,in combination with the handle, one or more wedges, 7L, driven into thelatter through said openings, the picl-liead having the holes 'z' t',and the fastening screw-bolt therefor, substantially as described.

The combination, in a pick, of a metallic socket part for receiving thehandle, having a central screw-threaded opening and openings On eachside thereof, in combination with one or more wedges driven into thehandle through said openings, the pick-head,

and the screw-bolt for securing the head upon the socket part over thesaid openings and their wedges, substantially as described.

4. The pick-socket part having its Outer end recessed at c and providedwith a solid part between said recess and the socket, having a centralscrew-threaded opening, f, and an opening, g, on each side Of saidcentral Opening, the said openings terminating in the socket and in therecess, combined with the handle secured over the inner ends of saidopenings, the Wedges 7L, driven through said openings g into the handle,the pickhead secured in the sockctrecess over the butt-ends of saidwedges, and the fasteningscrew, as shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
